To all whom it may concern:

Be it known that I, EMIL PREIN, subject of the King of Prussia, andresident at Hanover,- in the Province ofHanover, Kingdom of Prussia,German Empire, have invented certain new and useful Improvements inApparatus for WVeaving Fabrics, of which the following is aspecification.

This invention relates to apparatus for the weaving of fabrics, in whichthe filaments all lie close to the yarn.

During the process of weaving, there are always filaments which spreadout from the yarn, as is well known, even when they have been previouslyheld fast or previously prepared, or when the weaving takes place in themoist state, and this especially happens with the filaments of the warpyarn in con sequence of the mutual friction of the fila-' ments duringthe forming of the shed and in consequence of'the up-and-down motion ofthe reed blade, and also with the filaments of the weft yarn inconsequence of the suddenly occurring cessation of the adhesion of thefilaments during the shooting and rapid running out of the yarn and alsoin consequence of the attraction between the material which is runningout and that which remains behind. A portion ofthese filaments which areset free are bent, folded over and pressed down in the fabric by themotion of the reed during the throwing of the weft thread and owing tothethreads lying over it in the interwea ving. Thie filaments whichstill project from the fabric are subsequently removed by shearing andsingeing machines in order to render the fabric suitable for its variouspurposes. But by this process not only are a number of filaments whichpossess a great power of resistance to breakage, lost for the fabric,but the interweaving of the filaments which project and the forcibleremoval of the projecting filaments have also very serious drawbacks.The objection ,to the shearing is that the very sharp knives operatingat a great speed not only shear off the projecting filaments but also,any knots and threads which stick out and cut them clean away which isat first not noticed as damage and is only discovered on the applicationof tests for strength, whereupon one and the same fabric will giveuneven results. With the singeing process, the repeated sudden heatmakes all the woven filaments especially the unicellular cottonfilaments brittle.

It is a great drawback moreover that the bent andfoldedinterwoven fibersare held in the fabric with their power of projection unweakened. Ifthen at a later stage, the fabric is treated for some technical purpose,these filaments always again occur as points escaping out of the fabric,because their power of projection and the adhesive power of thepreparation act against each other. Also, when the bent fibers are heldduring the drying under mechanical pressure, which as is well known iseffected in various manners in technical weaving according to theapplication of the goods, they lie only restrained butnot cured. Theyhereafter also gradually free themselves from the bedding by reason ofthe various movements of the material, the alternative efiects oftemperature and of unequal wear, whereby much damage are caused.

The object of the present invention is a mechanism, shown in variousmodifications, which is intended to obviate the above mentioneddrawbacks. By means of this mech' anism, the warp threads are smoothedfiat immediately at the weaving point by a suit-- able means in themoist condition in such a way, that the projecting fibers are arrangedlengthwise against the threads, and are woven into the fabric in thisposition. Moreover, it is of especial importance that the application ofthe fibers to the yarn should take place just there and at that momentwhen forces tending to release the fibers can no longer act upon thethreads. As a suitable material for the moistening body, a rubber spongeis preferably made use of.

The invention comprises an arrangement whereby the support for themoistening body is attached to the loom shed so as to be capable ofmoving up and down and participate in its to-and-fro motion.

The device itself can be constructed in various forms.

In the accompanying drawing some of these forms are illustrated asfollows Figure 1 shows an elevation of the first construction incombination with the adjacent parts of the loom. The drawing shows theframe of the moistening body and the mechanism for moving it just beforethe application of the moisteningbody. Fig. 2 shows the same device inthe position after the application of the moistening body and during themoistening.

In all these figures, a indicates the lay sword, I) the lay, a the reed,d the breast plate of the loom. The warp threads are in i dicated by nand the finished fabric by 0.

The moistening body composed of spongy rubber or the like rests in along liquid container e which extends over the entire width of thefabric and possesses above a slotfor the exit of the moistening body.The liquidcontainer 0 is removably attached to the .part b andswingswith it to and fro. .By thearrangement of the moistening. body on theaforesaid part b there is efl'ecteda spe-: cially' favorablestrokingaction and the pos-. H

sibility of the easy arrangement of the separate parts of the movementis assured. The} moving and guidance of the moistening body,v and itsholder is effected by means of suit-, able rods and levers under theinfluence of the motion of the part I). At one end of the container is atubular support 7" to which by, means of a tube the apparatus can becon-' 'nected to a filling receptacle.

In-the constructional form illustrated in Figs. 1 and 2, the containereis detac-hably secured to a bar g, which possesses ,projections'h in theneighborhood of each end, to

which projections, two pivoted unequally long levers a and lcengage,whereby the bar is connected to the loom. For effecting of The boss 7'is gages the lower plane of the warp substan-' tially at the fell. Inconsequence of the unequal lengths of sults on the raising of themoistening'body a short backward motion thereof in regard to the partI). The consequence of this is that on the simultaneous motion of thepart b s the moistening body at the weaving point stands still for ashort moment. This causes the moisture therefrom to penetrate moreeffectively in the warp threads and to moisten these completely. Hereby-a better laying down of the fibers on the threads is effected.According to the length of the adjustable boss rthe period of contactcaIf be adjusted at will. As soon as the catch q has passed over theboss 1" it slides off it ,:and allows the limb 71 together with the bar.

the levers z and 70 there re-j 9 and the liquid container 6 with themoistening body to fall down. In order to hasten this rearward motionthere is provided a spring 't. In order toprevent any lifting ofthefabric on the engagement of the moisteningbody there is placed abovethe fabric throughout its whole length a lath a which is heldb-y theholders 4). The moistening of the completed fabric is prevented by aprotectivexband-wawhich is stretched beneath the fabric close up to thefell, and is secured at both sides as well .asbehind ina suitable Havingnow described my invention and in whatmanner. thesame is to be used,what I claim and desire to secure, is-

1. The combination witha loom having a lay, of moisteningmeans, guidedthereon, an-arm pivoted on the lay and having opera- .tive connectionwith said moistening means,

and astoponthe 100m frame to engage the said arm to cause the moisteningmeans to be raised on thebackward movement of the i lay.

links being longer than the other, a moisteningdevice pivoted-to saidlinks, an arm pivoted on. the bracketand having a pro- "jection engagingoneof the linksanda stop inthe path of the free end of said arm adaptedto engage the armas the layoscillates and thereby oscillate .said.moistening device.

'3. In apparatus of the character described,

.a loom frame,..a boss adjustably' fixed on said frame, a catch-leveradapted to move oversaid boss, alug on said catch-lever,

an arm engaged by said lug, a moisture holder:engaged by said arm, alink con- ,necting'the lower part of .said moisture holder to a block,and .a-spring drawing said container downward 'whereby said moistureholder is reciprocated intoand out of contact with the threads at theweaving point.

4. ,In apparatus of the character described,

. and having a moistening body just below the weaving-point, aprotective band to prevent contact of the -moistening body and thefabric.

5. Inapparatus of the-character described and having a ,moistening body,a bar disposed as acounter holder for the adjustment ofsaid moisteningbody.
